FAN.

SPECIFICATION forming part of Letters Patent No. 725,107, dated April14, 1903.

- Application filed October 9, 1901- Serial No. 78,054. (No modem To allwhom it may concern.-

Be it known that I, CLARENCE W; LUND, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented an Improved Fan, of which the following is aspecification.

This invention relates to fans.

A primary object of the invention is to provide a fan of the rotary typewhich is adapted to be operated by hand and which will be of simple andcheap construction.

A fan of my invention consists of the various features, combinations offeatures, and details of construction hereinafter described and claimed.

In the accompanying drawings a fan of my invention is fully illustrated.

Figure 1 is a front view of a fan of my invention. Fig. 2 is a side viewthereof. Fig. 3 is a rear view thereof, and Fig. 4 is a sectional viewon the line 4 4 of Fig. 3.

The fan 1 is of the rotary type and is secured to a drum 2, revolublymounted upon a stud or pin 3, which projects laterally from the upperend of an arm 4.

The fan 1 is adapted to be rotated by means of a cord 5, which passesaround the drum 2, said cord being attached at one side of the drum 2 toa spring or elastic 6, attached to a fixed support, and at the oppositeside of said drum being attached to an arm 7, supported in such mannerthat its upper end will be movable toward and from the upper end of thearm 4. The lower ends of the arms 4 and 7 form the handle of the fan,and the relation is such that pressing the lower ends of said armstoward each other will separate the upper ends of said arms. A spring 8,applied to said arms, operates to maintain the upper ends thereofnormally in positions of nearest approach to each other.

In the preferable construction shown the arms 4 and 7, the spring 8, andthe stud or pin 3, forming what may be called the fanframe, are made ofsteel wire and are all made integral with each other.

erable construction shown also the spring 8 is formed somewhat above thelower ends of the arms 4 and '7, the Wire being doubled upon itself toform a handle, which will be of such size that it may be grasped withcomof the arms 4 and 7 toward each other.

In the prof fort, and the lower ends of said arms convenientlycompressed to separate the upper ends thereof.

While I consider the construction above described as preferable, I donot desire to be limited thereto, as my invention admits of embodimentindifferent forms, as by pivoting the arms 4 and 7 directly to eachother and applying a spring thereto, so as to maintain said arms indesired normal relation.

My improved fan is operated by merely pressing the lower ends of thearms 4 and 7 together, which can be conveniently done by the handholding said fan and releasing them, allowing the spring 8 to returnsaid arms to their normal positions. In separating the upper ends ofsaid arms 4 and 7 the cord 5 bights upon the drum 2, which carriesthefan 1, causing said drum and fan to revolve. As soon as the arms arereleased the momentum of the revolving fan breaks the bight of the cord5 upon the drum 2 and the spring or elastic 6 operates to take up theslack of said cord due to the movement of the upper ends For this reasonthe fan 1 will preferably be made sufficiently heavy to acquire desiredmomentum. In addition to taking up the slack of the cord 5 the spring orelastic 6 also operates to produce necessary frictional engagement ofsaid cord with the drum 2 to rotate said fan.

I claim 1. The combination of a fan, a drum to which said fan issecured, an arm or support on which said drum is revolubly mounted, acord adjusted to said drum, a spring or elastic to which said cord isattached at one side of said drum and a pivotally-movable arm to whichsaid cord is attached at the opposite side of said drum, substantiallyas described.

2; The combination of a fan, a drum to which said fan is secured, an armor support on which said drum is revolubly mounted, a cord adjusted tosaid drum, a spring or elastic to which said cord is attached at oneside of said drum, a pivotally-movable arm to which said cord isattached at the opposite side of said drum and a spring applied to saidarm whereby said arm is maintained normally in position of nearestapproach to said drum, substantially as described.

3. The combination, in a fan, consisting of a drum provided with fanblades or vanes, of a frame c'omprising connected arms, the ends ofwhich are movable toward and from each other, and on one of which thedrum is revolubly mounted, a cord attached at one end to the other armand coiled about the drum, a spring or elastic attached at one end tothe other end of the cord, and at the other end to a part of the frame,substantially as described. I

4:. The combination of a fan, a drum to which said fan is secured,connected arms which are movable toward and from each other on one ofwhich said drum is revolubly mounted, a cord adjusted to said drum, aspring or elastic to which said cord is attached at one side of saiddrum, said cord being attached at the opposite side of said drum to thearm other than that on which said drum is mounted and a spring appliedto said arms and adapted to maintain said arms in such positions thatthe sections thereof on which said drum is mounted and to which saidcord is attached will normally be at their points of nearest approach toeach other, substantially as described.

5. The combination of a fan, a drum to which said fan is secured, arms,acoiled spring to which said arms are connected and which is adapted tomaintain the upper ends thereof normally at their points of nearestapproach to each other, said drum being revolubly mounted on one of saidarms, a cord adjusted to said drum, a spring or elastic to which saidcord is attached atone side of said drum, said cord being attached atthe opposite side of said drum to the arm other than that on which saiddrum is mounted, substantially as described.

6. The combination of a fan, a drum to which said fan is secured, arms,a coiled spring to which said arms are connected between their ends,said spring being adapted to maintain the upper ends of said armsnormally in positions of nearest approach to each other, said drum beingrevolubly mounted on one of said arms, a cord adjusted to said drum, aspring or elastic to which said cord is attached at one side of saiddrum, said cord being attached at the opposite side of said drum to thearm other than that on which said drum is mounted, substantially asdescribed.

7. The combination of a fan, a drum to which said fan is secured, arms,a coiled spring to which said arms are connected between their ends,said armsand spring being formed integral with each other and saidspring being adapted to maintain the upper ends of said arms normallyinpositions of nearest approach to each other, said drum being revolublymounted on one of said arms, a cord adjusted to said drum, a spring orelastic to which said cord is attached at one side of said drum, saidcord being attached at the opposite side of said drum to the arm otherthan that on which said drum is mounted, substantially as described.

In testimony that I claim the foregoing as my invention I affix mysignature, in presence of two subscribing witnesses, this 3d day ofOctober, A. D. 1901.
